Rafael's Grandpa offered Rataol a choice of two different options. The first option is to give Rafael $125 each year for the next two years. The second option is to give Rafael $1 for every $4 that he is able to save over the next two years
Part A
Rafael believes he can save a total of $755 over the next two years. Would the first option or the second option be a better choice for Rafael? Show your work
Part 8
How much money at a minimum would Rafael need to save for the second option to be a better choice than the first option? Show your work

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
